"Portable desktop" or Laptop

Answering someone's question about laptops got me thinking. How many people with a laptop actually use it more like a portable desktop (mostly plugged in a wall outlet)?

I think that's way most of them should be, have it plugged when you're at home or a place where you can have it plugged and use the batter when you're on the go

My laptop is used quite a bit for travel, and when travelling it gets plugged in very little. But I also use it at home quite a bit as a remote terminal, and too keep from cycling the battery so many times I usually plug it in when at home.

My laptop is never intended to be a desktop replacement, and battery life and use with the battery is important, but if I'm going to set it up on the dining table and use it for more than a few hours, it is actually more convenient to go ahead and plug it in and not worry about the battery running down, the machine wanting to go to sleep mode if I step away to go to the bathroom, or wanting to continually dim the screen.
